The 49ers offset Colin Kaepernick’s new contract with the money officially gained from Carlos Rogers’ deal being wiped from the books last week.
Those moves, along with the signing of special-teams player Blake Costanzo, leaves the 49ers with $5.725 million in cap space, according to NFL Players Association figures.
The 49ers have some room to maneuver under the cap, but there is no indication they are close to any new deals with players who are seeking extensions. Tight end Vernon Davis and guard Alex Boone have not taken part in the team's voluntary offseason program due to their desires to land new contracts.
Only the top 51 players count against the salary cap in the offseason. After the final cuts before the start of the regular season, all money devoted to players contracts count against the salary cap.
Kaepernick last week became the sixth-highest-paid quarterback in the NFL with his $115 million extension through the 2020 season, which includes a $12.328 signing bonus. He counts $3,767,444 against the salary cap this season. The 49ers gained $6.6 million in cap space with the post-June 1 designation when they released Rogers in March to receive maximum salary-cap relief.
The 49ers did not deliver Costanzo any guaranteed money on his one-year, $855,000 deal. The 49ers receive the minimum salary benefit, which lowers Costanzo’s cap figure to $570,000.
